Open Laparoscopic-assisted Repair of Abdominal Wall Hernia and Bulge

Abstract

Summary: Rectus abdominalis musculocutaneous (RAM) flaps have numerous uses in the treatment of large defects. However, flap harvesting can result in abdominal wall incisional hernia and bulge, which are challenging problems. Most of these problems occur below the arcuate line abdominal wall. However, there will be differences that are unique to each patient in the area of hernia or bulge. The open approach repair appears to be used most often, but the precise area of hernia and bulge is often not distinguished. This report describes a case that was treated using a new repair method, which had the clear advantage of allowing the precise area of abdominal wall weakness to be recognized. A 53-year-old man underwent left vertical RAM flap for reconstruction after tongue carcinoma resection. Six months after the operation, lower abdominal wall hernia and bulge were observed. Open laparoscopic-assisted repair was performed. Pneumoperitoneum led to distension of the abdominal cavity and outward stretching of the abdominal wall, so that the area of hernia and bulge protruded to a great degree. In this phase, by making the operating room slightly dark, the area became more clearly recognizable. When direct plication of the hernia and bulging area was required, the contralateral component separation technique was performed. This study describes an inventive repair procedure for abdominal wall hernia or bulge after RAM flap, with the combined advantages of open and laparoscopic repair.
